Using HTML Targets
In HTML, the target attribute is used to specify where to open the linked document (anchor - a).
There are 5 different features available.
The _blank value opens the linked document in a new window or tab.
The _self value opens the linked document in the same document. Since this property is the default, if no target is specified in a (anchor), then the value "_self" is considered valid.
The _parent value opens the linked document in the parent frame.
The _top value opens the linked document in the full body of the window.
The frame name value opens the linked document in the specified named frame.
